CLARK CHIDDISTER, OF DECATUR, INDIANA.

GATE.

SPECIFICATION forming part of Letters Patent No. 401,008, dated April 9,1889.

' Application filed January 3, 1889- Serial No. 295 ,290. (No model.)

To all whom t may concern.-

Be it known that I, CLARK CHIDDIsTER, a citizen of the United States,residing at Decatur, in the county of Adams and State of Indiana, haveinvented certain new and useful Improvements in Gates; and I do herebydeclare the following to be a full, clear, and evract description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the saine.

My invention relates to gates, and more particularly to that class knownas tilting gates.

The object I have in vview is to construct a gate which will beadjustable and more simple, cheap, and durable, and also moreeffectively operated than those hitherto in use.

With these ends in View my invention consists in certain peculiarfeatures and combin ttions of parts more fully described hereinafter,and pointed out in the claims.

Referring to the accompanying' drawings, Figure l ,represents aperspective view of my complete device; Fig. 2, a rear View, a portionof the gate being broken away; and Fig. 3, a longitudinal section of thegate detached from the frame.

The reference-letter A indicates the latchpost, which is firmly set inthe ground and provided near its lower extremity with a seat, d, whichsupports the front end of the gate when in closed position. It also hasnear its top a pair of guides, b, which prevent the gate from lateralplay, and an aperture, c, which engages the bolt that locks the gate.

B is the gate, which is constructed with vertical bars C D E F andhorizontal bars G, H, I, and J, which are made of iron and screwthreadedat both ends and their forward ends secured in the vertical bar F in anysuitable manner, such as by the nuts d. The other vertical bars, C, D,and E, are each formed in two pieces,which are adapted to`be placed oneither side of the horizontal bars and firmly clamped together by meansof the bolts or rivets e. The rear ends of the horizontal bars aresupported and held in place between the two sections of the rearvertical bar, C, by means of bolts f, passed across between the twosections above and below the horizontal bars, which are provided withnuts g on their rear ends in the same manner as at their outer ends. Thegate is also provided with a crossbrace, K, extending from the top ofthe forward vertical bar, F, to the bottom of the rear vertical bar, C,and formed in two pieces adapted to be placed on either side of thegate, mortised into the vertical bars D and E, and riveted together bythe bolts h, passed through above and below the horizontal bars G, II,and I.

A barbed wire, L, is fastened to the vertical bar F, passing through thebars D and E, and connected to a screw-'threaded bolt M, which iscontained between the two sections of the rear vertical bar, C, and heldin place by the bolts t', passed across between the two sections of thebar C, above and below said bolt M. This bolt is alsoY provided with anut, N, by means of which the wire can be tightened whenever it becomesnecessary.

The gates being bolted together in the manner above describedfacilitates its being tightened when it has become loose from 'frequentuse or by action of the weather. The gate is further strengthened by thelateral braces OO, which are secured at their outer ends to a bolt, j,passed through the verticalbar D and t-he cross-brace K, and at theirinner ends to a rock-shaft, P. This rock-shaft P is placed at rightangles to the gate, and is mortised into each section of the rearvertical bar, C, and firmly fastened to the same by the bolts m. Thisrock-shaft P is journaled at either end in a pair of upright standards,R, which are each provided with a removable cap, a, over the journals tofacilitate lubricating them when necessary. These upright standards Rare rmly planted in the ground on either side of the gate, and arereenforced by a pair of short posts, r, driven into the ground besideeither standard and screwed to the same.

At a convenient height upon each standard a hand-lever, S, is pivoted atan angle of about sixty degrees to the standards, and their long armsform handles with which to operate the gate. Enough space is leftbetween inner ends of the short arms a; c to allow the gate to passbetween them when it is thrown back. A rope or piece of cord, t, may beattached to the outer arm or handle of each le- IOO ver to facilitateoperating the same. A pair of eyes, a u, are fastened into the lowercxtremities of the levers S and engage a pair of rods, T T, which are ofequal length, and pass down on either side of the gate to the bellcranklever U, to which they are attached. This bell-crank lever U isfulcrumed on the vertical bar D, just above the cross-brace K, andconsists of a rod bent in the forni of a yoke, y, and passed on eitherside ot' the gate, around the pivot e, (which passes through thevertical bar D andthe horizontal bar I,) and thence bent to form shortarms V of equal length, which are connected, respectively, to the lowerextremities of the rods T T. lVhen the gate is closed, the yoke y of thebellcrank lever rests against the back side of the bar D, while the armsV V extend parallel with the cross-brace K. It will thus be seen thatthe arrangement on each side of the gate is precisely the saine, andtherefore the gate can be operated as well from one side as from theother. The yoke y of the lever is placed astride a locking-bolt, Z, andis held in place thereon by means of a projection, c', formed upon saidbolt, against which it bears. This bolt Z is situated just above thehorizontal bar II of the gate and passes between the two sections of thevertical bars D and E and the crossbrace K and into the hole a. in thevertical bar F, and enters the aperture c in the latch-post A, which isprovided with a roller, to facilitate the movement of the bolt. Thisbolt is provided between the vertical bars E and F with a spring, a2,which bears against a plate, b', secured to the bar E, and holds thebolt in locking adjustment until withdrawn by the action of thebellcrank lever U. The forward and backward movement of the bolt islimited by means of a pin, c', which passes through the vertical bar Eand engages the walls of alongitudinal slot, d', in the bolt Z.

The construction of my devicehavin g been set forth, I will now proceedto describe its operation. A person walking, riding, or driving, whowishes to pass through the gate, grasps the handle of one of the leversS, or, if he cannot reach the handle, the rope t, and pulls down uponthe same. This action will raise the short arm x of the lever, andthereby the rod T connected thereto. ing connected at its lowerextremity to one of the short arms V ot the bell-crank lever U, raisesthe same, which operation throws back the yoke Iy of said lever andthereby withdraws the bolt Z. The opposite lever and connection willoperate simultaneously with the parts just described. The gate will thusbe released from the latching-post, and when This rod, be!

the bolt reaches the limit of it-s backward movement will be raised andthrown back between the standards R and assume a vertical position, therear vertical bar, C, resting on the ground. Vhen the gate is in thisopen position, the lower ends of the rods T T are carried back of thepivotal point of the gate, so that when the operator has passed throughby pulling down upon the handle of the opposite lever the gate will beraised from its vertical position and thrown back and locked by means ofthe spring-actuated bolt Z.

My device can easily be employed as a iieldgate by substituting ropesand weights for the operating-levers.

It is evident that many slight changes which might suggest themselves toa skilled mechanic might be resorted to without departing from thespirit and scope of my invention; hence l do not limit myself to theprecise construction herein shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a tilting gate, a pair of hand-levers pivoted to uprightstandards, a bell-crank lever pivoted to the gate and consisting of arod bent to form a yoke and extending on either side of the gate, and aspriiigactuated bolt engaged by said yoke and operated thereby, in themanner and for the purpose described.

2. In a tilting gate, the combination of a pair of hand-levers pivotedto upright standards erected on either side of the gate, a bellcranklever consisting of a U-shaped portion anda pair of short armslocated oneither side of the gate, a pair of rods connecting the hand-levers andthe short arms of the bell crank lever, and a springactuated boltengaged by the U-shaped portion of said bellcrank lever and operatedthereby, all arranged and adapted to operate as set forth.

3. In a tilting gate, a bell-crank lever piv oted to the gate andconsisting' of a U-shaped portion and a pair of short arms extending oneither side ot' the gate, in combination with a pair of hand-levers, aspring-actuated bolt, a projection upon the end of said bolt en gagingthe U-shaped portion of the bell-crank lever, and a slot in said boltengaged by a pin which limits the play of the bolt, sul)- stantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
